A more thorough explanation:

Definition: Dispute is both a verb and a noun. A dispute is a disagreement, argument, or controversy that often leads to a legal proceeding, such as arbitration, mediation, or a lawsuit. The opposing parties are said to be adverse to one another. To dispute is the corresponding verb, which means to participate in a dispute or to make a particular argument in a dispute.

Noun: The two neighbors had a dispute over the property line, which led to a lawsuit.

Verb: The company disputed the claims made by the customer and provided evidence to support their position.

These examples illustrate how a dispute can lead to a legal proceeding and how parties can make arguments to support their position.
